This project deals with the comparison and implementation of approaches of self-explaining roads. It mainly aims to bridge the gap between fundamental knowledge concerning self-explaining roads and the practical, hands-on knowledge that road authorities require to make their roads safer by applying the concept of self-explaining roads. The starting point is the relevant fundamental knowledge that exists on different approaches to self-explaining roads, which will be compared and evaluated.

Subsequently, this project illustrates two feasible steps towards a useful checklist that road authorities in different European countries can use, which will enhance transnational benefits. These steps will be piloted in different European countries, so as to advance towards a common European approach to self-explaining roads. The first step focuses on ascertaining road users' ability to recognise specific categories of roads and understand their context. In the second step, these results will be implemented in the development of a decision support tool for road authorities. This tool will essentially be a checklist road authorities can use to determine the extent to which their roads are self-explaining, but also contains information concerning design elements that can help to make roads more selfexplaining. As road authorities are the target group, they will be actively involved throughout this project, quite specifically in assessing the feasibility of the pilots we propose and they will also play a significant role in the dissemination process.
